URINAL-WASHOUT.

SPECIFICATION forming part of Letters Patent No. 456,73, dated July 14, 1891. Application iled June 7, .1890. Serial No. 354,615. (No model.)

To all whom t may concern:

Be it known that I, PETER WHITE, of the city of St. Louis, inthe State of Missouri, have invented a certain new and useful Improvement in Urinal-Washouts, of which the following is a full, clear, and exact description, referencel being had to the accompanyitng drawings, forming a part of lthis specificaion.

My invention relates to an improved Washout for urinals, which is automatic in its operation; and my invention 'consists in featu-res of novelty hereinafter fully described, and pointed out in the claims.

Figure l is an elevation illustrative of my invention, the tank or cistern bei-ng partly broken away and the bowl-trap being shown in section. Fig. 2 is avertical section through the tank and the parts located within it, showing the parts in the position they assume just after the flush has been broken. Fig. 3 is a similar view showing the parts in the position they assume just after the ush has commenced. Fig. 4 is a similar view showing the parts in the position they assume after the iush has been working for a time, but before it is broken.

Referring to vthe drawings, A represents the bowls of a urinal; B, a discharge-pipe; C, a trap in the discharge-pipe; D, a watertank or cistern; E, a pipe through which the water is supplied to the tank or cistern, and F is a pipe forming a communication between the tank and bowls.

G represents the short leg, and Hthe long leg, of a siphon located in the tank D, the short leg communicating at bottom with the tank and the long leg being connected to the discharge-pipe F, which leads to the bowls A.

I represents la valvecontrolling a port or passage J in the long leg of the Siphon. The valve is pivoted at K and is provided with a stem carrying an adjustable float L.

M represents a valve located in a housing N on the upper end of the pipe E within the tank D. The valve has an upper packing M and a lower packing M2, and it is connected by a link O to a lever O', provided with an adjustable fioat'O2 and pivoted at O3 to an arm O4, formed upon or secured to thehousing N. The valve M controls the opening P between the upper end of the pipe E andthe hollow open-ended housing N, and it is provided with a plug Q, having an opening Q', which is extended through the side of the valve next to the pipe E, as shown in Fig. 2.

R represents a pipe forming a communication between the trap O and the upper end of the siphon G H. This pipe is provided with a housing S at its upper end, in which fits a double valve, consisting of a valve T on a stem T, the stem having a valve T2 beneath the housing, and which fits, when in its upper position, against a seat T3, formed by the lower end of the housing. The stem `T is provided with an adjustable oat T4.

The portion of the valve-stem T5 which its within the housing S is so formed that while it tits the opening in which it works yet it permits the passage of air when the lower valve is open, as shown in Figs. 2 and 4. Its

shape may be annular and provided with a groove for the passage of the air, or it may be made in the form of radial wings, as shown in-Figs. 2, 3, and 4, which, while they guide the valves, do not interfere with the passage of the air when the valve is open. The housing S has a seat S for the upper valve T.

The housing has also a passage or port U, forming a communication between the pipe R and the opening in the housing in which the valve-stem T5 fits, and it has an opening U', forming a communication between the opening in which the valve-stem tits and the upper end R of the pipe R.

The operation is as follows: Supposing the vtank t0 be full of water, as shown in Fig. 3,

the siphonic action of the water in the Siphon G H will be formed and the water will pass from the tank to the bowls, as shown by the featherless arrows, Fig. At the same time there is an upward suction through the pipe R R and the ports U U', as shown by the full arrows in Fig. 3, which rarefies the air in the trap C, causing the siphonic action to take place in the trap O, the bowls, of course,

4being iiushed and cleansed by the water as it passes from the tank to the trap, which cominunicates, as usual, with a discharge-pipe.r Now as the water -is reduced inthe tank D IOO the valve M closes or moves from the position shown in Fig. 3 to the position shown in Fig. l, thus shutting off the main supply of water through the pipe E, the valve M being permitted to close by the water leaving the fioat O2,which counterbalances the valve an d forces it to its lower position or the position shown in Fig. 2. When the water in the tank D is reduced to about the amount shown in Fig. 4, the valve-stem T drops, (owing to the water leaving the float T2) causing the valve T2 to open or leave its seat T3 and the valve T to be closed, as shown in Figs. 2 and 4. Air is now permitted to pass through the pipe R, as shown by the arrows in Figs. 2 and 4, breaking the siphon in the trap C, but is prevented by the valve T from passing into the siphon G H. As the water in t-he tank D is reduced still more than shown -in Fig. 4, and to about the amount shown in Fig. 2, the valve I opens, (owing to the water leaving the float L,) admitting air through the opening J and breaking the siphonic action in the siphon G H. The water will then cease to pass from the tank to the bowls; but it will continue to flow in a small quantity from the pipe E into the tank D, the quantity being regulated by the opening Qin the plug' Q,the plug being turned to regulate the communication between the opening in the plug and the opening in the housing between the plug and the pipe E. As the water enters the tank through the pipe E and the plug Q, as shown by the featherless arrows in Fig'. 2, it first lifts the float L and closes the valve l, and as it continues to enter it lifts the fioat T4 and closes the valve T2, and as the tank still continues to fill the water lifts the float O2, raising the valve M and opening a free communication between the pipe and the tank, this taking place just before the tank is about full. This rush of water starts the water in the siphon G H, as shown in Fig. 3, and the tank begins to empty again, as explained. The operation thus goes on continuously, the parts all working automatically and continuing to iiush the bowls.

If it is desired to stop the action of the the parts, it is of course onlynecessary to provide the pipe E with a valve which can be closed at will.

By adjusting the iioats L, T4, and O2 the various valves may be regulated at will.
